Laryngopharyngeal reflux (LPR) represents a challenging field. Therapeutic studies of proton pump inhibitors in LPR have shown mixed results. The Restech pH catheter (Respiratory Technology Corp., San Diego, CA) is a minimally invasive device for detection of oropharyngeal acid reflux. The aim of this study was to provide normative data using this device in both distal esophagus and oropharynx.

In vitro and in vivo studies were performed to systematically assess the performance characteristics of an oropharyngeal pH probe to diagnose gastro‐esophageal reflux disease and show limited sensitivity.

Gastroesophageal reflux evaluation in patients affected by chronic cough: Restech versus multichannel intraluminal impedance/pH metry

Oropharyngeal pH monitoring has been developed to detect supra‐esophageal gastric reflux (SEGR) and multichannel intraluminal impedance/ pH monitoring (MII/pH) was compared.

The objective of this study was to establish a simple and reliable scoring system for evaluating LPR consisting of both subjective and objective criteria.

Correlation of salivary and nasal lavage pepsin with MII‐pH testing

Laryngopharyngeal reflux (LPR) is a common upper airway disease. Salivary pepsin is a proposed marker for LPR; however, the optimal time for collection of specimens for pepsin detection and pepsin's

Pharyngeal pH and Impedance Monitoring

Further outcome studies are needed to assess the role of ­pharyngeal impedance and pH monitoring in this group of patients and to determine who might symptomatically benefit from medical or surgical intervention.
